It seems you have a few options. IDLgrSurface objects, mesh_obj "extrude" +
IDLgrPolygon, and as David mentioned Streamline.
I think the easiest would be creating many Surface objects and specifying
x,y, and z accordingly. You'll have to do some work to get your data into
the correct format but once you work out the details it should be easy.
say you have a 2d array of data, each column you wish to plot as a ribbon:
pro ribbon_plot, data, colors, model, container
width = 2.5
space = 1.0
s = size(data, /dimensions)
surf_array = objarr(s[0])
container -> add, surf_array
for n=0, s[0]-1 do begin
z = [data[n,*], data[n,*]]
x = [n * (width + space), (n * (width + space)) + width]
y = findgen(s[1])
surf_array[n] = obj_new('idlgrsurface',z, x, y, color=colors[*,n], $
style=2)
endfor
model -> add, surf_array
model -> rotate, [1,0,0], -90.
end
I left a lot of room for style points but this should get you started.

It's not clear to me what you are trying to do,
but have you had a look at the STREAMLINE command?
That is suppose to draw ribbon plots.
Cheers,
David
